Integration of a stochastic differential equation (SDE) for a user particle variable (attribute).
![\[ \frac{dV}{dt} = \frac{V - PIP}{TCARAC} \]](form_496.png) 
When there is interaction with a boundary face, the integration degenerates to order 1 (even if the 2nd order scheme is active).

| [in] | tcarac | variable characteristic time |
